Correlation coefficients are handy tools that help us see how two things are related. When we calculate a correlation coefficient, we get a number between -1 and 1. Let’s break down what these numbers mean:
For example, let’s look at how hours studied relate to exam scores. If we get a correlation coefficient of 0.85, this shows a strong positive relationship. It suggests that more study hours likely lead to better scores.
But it’s really important to understand that correlation doesn't mean causation. Just because two things are related doesn’t mean one is causing the other.
For instance, ice cream sales might go up at the same time as drowning incidents, but that doesn’t mean ice cream is causing drowning!
Knowing this difference is very important when we look at data.
